Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 812,735, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 812,735 | |
| -1 | -812,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 812,735.
Example:
1 x 812,735 = 812,735
and
-1 x -812,735 = 812,735
Notice both answers equal 812,735
With that explanation out of the way, let's continue. Next, we take the number 812,735 and divide it by 2:
812,735 ÷ 2 = 406,367.5
If the quotient is a whole number, then 2 and 406,367.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 812,735 | |
| -1 | -812,735 |
Now, we try dividing 812,735 by 3:
812,735 ÷ 3 = 270,911.6667
If the quotient is a whole number, then 3 and 270,911.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 812,735 | |
| -1 | -812,735 |
Let's try dividing by 4:
812,735 ÷ 4 = 203,183.75
If the quotient is a whole number, then 4 and 203,183.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 812,735 | |
| -1 | 812,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 2,111 | 10,555 | 14,777 | 23,221 | 73,885 | 116,105 | 162,547 | 812,735 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -2,111 | -10,555 | -14,777 | -23,221 | -73,885 | -116,105 | -162,547 | -812,735 |
